Awesome question, actually! My sister in law had a couch this shape (L shaped, asymmetrical). And it was oriented this way, with the TV across from the short end. I don't think that's quite right, but they had a narrow room. I'd put the TV facing the long side, so four people can sit. Come to think of it, that's how my uncle did it with his.

At my sister-in-law's place (she's since moved, so this is going back about 20 years now!) I sat on the space between the leftmost two cushions as you look at it. That won't be comfortable on every couch. It was on hers. The reason was, she always took the corner, but she was small and kinda nestled herself in there. My nephew would lay to the far right with his elbows up on the end. It seems to me that most little boys like to lay down in the most uncomfortable position possible, and as long as they're tuned into what's on TV, they're happy to do so. My SIL's loser boyfriend would be between them, under her legs. As for my niece, her spot was next to wherever I was, so because she was so small, I'd sit half a space from the end, and she'd wiggle into the end space.
